Help required for CNG setting

[ya123]

Hi PW members,

My Mehran car is consuming too much gas, Rs. 180-190 on 57 Kms daily (is this right ??). i want to readjust the CNG flow. your help is required

when i tight the mentioned screw in image, the car shakes /vibrates (means low gas flow -- am i right ?? ) and when i loose it little until car shakes are vanished (means more gas flow).

but when i loose too much it shakes again and about to stop.. why ?? what does this mean ?

kindly tell me correct way to adjust this ? i want that there should be low gas consumption

Yeah that is pretty low mileage.. Go for cleaning of the kit and the cylinder and tuning...
